[0034] This application provides a vehicle 1000, which can be a pure gasoline vehicle, a pure electric vehicle, a hybrid electric vehicle, etc. The vehicle 1000 can also be a sedan, bus, truck, trailer, etc. This application does not specifically limit the type of vehicle 1000.

[0035] In some embodiments, see Figure 1 , Figure 1 This is a structural schematic diagram of a vehicle 1000 provided in an embodiment of this application. The vehicle 1000 includes a body 100 and a seat 200. The seat 200 is connected to the body 100 and located within the passenger space of the vehicle 1000 for passengers to ride in.

[0036] It should be noted that the seat 200 can be used not only in vehicles 1000, but also in other equipment such as ships and airplanes.

[0037] In some embodiments, the seat 200 includes a seat support assembly 10 and a wrapping member. The seat support assembly 10 forms a support frame for the seat 200, and the wrapping member wraps around the seat support assembly 10 and forms the outer surface of the seat 200.

[0038] In some implementations, see Figure 2 , Figure 2 for Figure 1 The diagram shows the structure of the seat support assembly 10 of the seat 200 in the vehicle 1000. The seat support assembly 10 includes a seat support 2 and a connecting structure 1. The connecting structure 1 is connected to the seat support 2 and is used to connect to a child seat to fix the child seat to the seat 200 of the vehicle 1000.

[0039] In some implementations, see Figure 2 and Figure 3 , Figure 3 for Figure 2The diagram shows the structure of the connecting structure 1 in the seat bracket assembly 10. The connecting structure 1 includes a hook 11 and a connector 12 connected to the hook 11. The hook 11 is adapted to be connected to the child seat, and the connector 12 is adapted to be detachably connected to the seat bracket 2 of the vehicle 1000.

[0040] In the above solution, the hook-on 11 is connected to the connector 12, and the connector 12 is detachably connected to the seat bracket 2 of the vehicle 1000. In this way, the hook-on 11 and the connector 12 form a modular structure, and the connector 12 can be connected to various seat brackets 2, which can improve the versatility of the connection structure 1 of the child seat.

[0041] It should be noted that the existing child seat connection structure 1 is connected to the seat frame 2 via welding. Because the structure of the seat frame 2 differs between different models of seats 200, the welding fixtures and gauges used when welding the connection structure 1 to different seat frames 2 are not interchangeable.

[0042] In this application, the connecting structure 1 of the child seat is modularly designed. As long as the seat bracket 2 is set in the installation position, it can be connected to the connecting structure 1, which can be applied to different models of seats 200, thus improving the versatility of the connecting structure 1.

[0043] It should be noted that the connector 11 is made of bent steel wire. The diameter of the steel wire and the dimensions of the connector 11 can be set with reference to the dimensions of existing child seat connection structures.

[0044] For example, the diameter of the steel wire can be 6mm.

[0045] For example, the width of the space accommodating the hook 11 is 30mm.

[0046] In some examples, there are two hooks 11, which are spaced apart along the width of the seat 200.

[0047] In some implementations, see Figure 3 The connector 12 includes a first connector 121 and a second connector 123. The hanger 11 is fixedly connected to the first connector 121, and the second connector 123 cooperates with the first connector 121 to be detachably connected to the seat bracket 2 of the vehicle 1000.

[0048] In the above solution, the first connector 121 and the second connector 123 are combined to achieve a detachable connection between the connector 12 and the seat bracket 2 of the vehicle 1000. The connection structure 1 is simple, easy to install and disassemble, and improves the convenience of connecting the connection structure 1 and the seat bracket 2.

[0049] In some specific implementation methods, see [reference] Figure 3The first connector 121 includes one of a bolt and a nut, and the second connector 123 includes the other of a bolt and a nut, the bolt and nut engaging to be detachably connected to the seat bracket 2 of the vehicle 1000.

[0050] In the above solution, the connecting structure 1 is detachably connected to the seat bracket 2 of the vehicle 1000 using bolts and nuts. The connection method is simple and easy to operate.

[0051] In some examples, the first connector 121 includes a bolt, and the second connector 123 includes a nut. For example, the nut is fixedly connected to the seat bracket 2, and after the bolt and nut are connected, the connecting structure 1 is detachably connected to the seat bracket 2.

[0052] In other examples, the first connector 121 includes a nut, and the second connector 123 includes a bolt. For example, the nut is fixedly connected to the first connector 121, and the bolt passes through the seat bracket 2 and is connected to the nut.

[0053] In some other embodiments, the seat support 2 includes a crossbeam 21. A first connector 121 is a first hinge, and a second connector 123 is a second hinge. One end of the first hinge is hinged to one end of the second hinge. The first hinge is located on one side of the crossbeam 21. After the other end of the first hinge is connected to the other end of the second hinge, the first hinge and the second hinge surround the periphery of the crossbeam 21, so that the connecting structure 1 is detachably connected to the seat support 2 through the cooperation of the first connector 121 and the second connector 123.

[0054] The other end of the first hinge member and the other end of the second hinge member can be connected by a pin. For example, the other end of the first hinge member is provided with a receiving groove to accommodate the other end of the second hinge member, and the groove walls on both sides of the receiving groove and the other end of the second hinge member are provided with through holes for the pin to pass through.

[0055] In some implementations, see Figure 3 The first connector 121 also includes a support 122, which is fixed to one of a bolt and a nut, and the hanger 11 is fixedly connected to the support 122.

[0056] In the above solution, one of the bolt and nut is fixedly connected to the hanger 11 by the support member 122, so that when the bolt and nut are engaged, the hanger 11 can be detachably connected to the seat bracket 2. The structure is simple and easy to process and produce.

[0057] In some examples, the support member 122 can be a flat plate. In order to improve the strength of the support member 122, a concave-convex structure 122b can be machined on the flat plate.

[0058] In other examples, the support member 122 can be a profile with a certain length, such as channel steel or I-beam, to improve the strength of the support member 122.

[0059] In some examples, the hanger 11 has a second connecting portion 111, which is welded to the support member 122. The portion of the hanger 11 other than the second connecting portion 111 has a U-shaped structure. The hanger 11 may have two second connecting portions 111, which are respectively connected to the two ends of the U-shaped structure.

[0060] In other examples, the second connecting portion 111 of the hanger 11 can be a flat structure, and a connecting hole is provided in the second connecting portion 111, through which a screw is passed to connect to the support 122.

[0061] In some examples, the support member 122 is connected to a bolt. The support member 122 can be movably connected to the bolt, for example, by providing a through hole in the support portion through which the bolt movably passes. Alternatively, the support member 122 can be fixedly connected to the bolt, for example, by welding the support member 122 to the bolt after the bolt passes through the through hole.

[0062] In other examples, the support 122 is connected to a nut. The support 122 may be welded to the nut.

[0063] In some implementations, see Figure 2 and Figure 3 The first connector 121 is provided with an anti-rotation part 122a, which is adapted to cooperate with the seat bracket 2 to prevent the hook 11 from rotating relative to the seat bracket 2.

[0064] In the above solution, the first connector 121 is provided with an anti-rotation part 122a, which cooperates with the seat bracket 2 to prevent the hook 11 from rotating relative to the seat bracket 2, thereby improving the stability of the hook 11 relative to the seat bracket 2. Since the hook 11 is used to connect with the child seat, it can improve the stability of the child seat after it is connected to the connecting structure 1.

[0065] In some examples, the first connector 121 includes a support 122, which may be a flat plate. The anti-rotation portion 122a is a first bend provided on one side edge of the flat plate, extending toward the side opposite to the hook member 11. The seat bracket 2 is provided with a connection hole that can accommodate the first bend, which engages with the connection hole to prevent the hook member 11 from rotating relative to the seat bracket 2.

[0066] In addition, the first bend portion cooperates with the connecting hole of the seat bracket 2. When the connecting structure 1 is subjected to lateral force, the first bend portion and the connecting hole simultaneously bear the lateral force, which can improve the stress performance of the connecting structure 1.

[0067] In other examples, the anti-rotation part 122a may be a second bend provided on the hook member 11. For example, the two sides of the hook member 11 are bent toward the side opposite to the U-shaped structure to form two second bends, and the seat bracket 2 is provided with two corresponding round holes to accommodate the two second bends respectively, so as to prevent the hook member 11 from rotating relative to the seat bracket 2.

[0068] In some implementations, see Figure 2 , Figure 3 and Figure 4 The seat support 2 includes a crossbeam 21, and the connecting structure 1 is detachably connected to the crossbeam 21.

[0069] In the above scheme, the seat bracket 2 is provided with a crossbeam 21, and the connecting structure 1 is detachably connected to the crossbeam 21. An operating space can be provided below the crossbeam 21, which can improve the convenience of connecting the connecting structure 1 and the seat bracket 2.

[0070] In some examples, the crossbeam 21 includes a beam body 214 and supports 211 connected to both sides of the beam body 214. The connecting structure 1 is connected to the beam body 214, and the supports 211 are used to connect to the body 100 of the vehicle 1000.

[0071] For example, the support 211 and the beam 214 can be integrally formed.

[0072] For example, the support 211 and the beam 214 are separate structures, connected by fasteners such as bolts.

[0073] In some examples, the support 122 is fixedly connected to the nut and is located on the side of the beam 214 facing away from the vehicle body 100. Bolts pass through the beam 214 from the side of the beam 214 facing the vehicle body 100 and are connected to the nut to fix the connecting structure 1 to the crossbeam 21.

[0074] In other examples, the crossbeam 21 can be a cylindrical crossbeam 21, and a flat structure can be added at the connection between the crossbeam 21 and the connecting structure 1, with through holes machined in the flat structure. The support member 122 is fixedly connected to the nut and is located on the side of the crossbeam 21 facing away from the vehicle body 100. Bolts pass through the through holes from the side of the crossbeam 21 facing the vehicle body 100 and are connected to the nut to fix the connecting structure 1 to the crossbeam 21.

[0075] In some examples, the crossbeam 21 is provided with a mounting portion 212, which is connected to the connecting structure 1. The mounting portion 212 is provided with a first protrusion 212a and a second protrusion 212b along the length of the crossbeam 21, and at least a portion of the connecting structure 1 is located between the first protrusion 212a and the second protrusion 212b.

[0076] The first protrusion 212a and the second protrusion 212b can limit the connection structure 1, which facilitates the quick connection between the connection structure 1 and the crossbeam 21 and prevents the connection structure 1 from moving relative to the crossbeam 21 along the length direction of the crossbeam 21.

[0077] In some implementations, see Figure 2 and Figure 4 The seat support 2 includes a backrest 22 and a crossbeam 21, wherein the backrest 22 and / or the crossbeam 21 are made of magnesium alloy.

[0078] In the above solution, the backrest 22 and / or crossbeam 21 of the seat bracket 2 are made of magnesium alloy, which can enhance the strength of the seat bracket 2 and reduce its weight compared to steel parts.

[0079] It should be noted that, within the elastic range, magnesium alloy parts absorb about 50% more energy than aluminum alloy parts when subjected to impact loads. Therefore, the backrest 22 and crossbeam of the seat bracket 2 are made of magnesium alloy parts, which also have good shock absorption and noise reduction performance.

[0080] In some examples, the backrest 22 is rotatably connected to the crossbeam 21 so that the angle of the backrest 22 relative to the crossbeam 21 is adjustable.

[0081] In some examples, the backrest 22 is connected to the crossbeam 21 via a connecting plate 23. One end of the connecting plate 23 is rotatably connected to the backrest 22, and the other end is connected to the crossbeam 21, so that the angle of the backrest 22 relative to the crossbeam 21 is adjustable. For example, each end of the crossbeam 21 is provided with a first connecting portion 213, and the backrest 22 is detachably connected to the connecting plate 23 via the first connecting portion 213.

[0082] In some examples, the backrest 22 is made of magnesium alloy to reduce its weight and increase its strength.

[0083] In other examples, the crossbeam 21 is made of magnesium alloy to reduce its weight and increase its strength.

[0084] In some other examples, both the crossbeam 21 and the backrest 22 are made of magnesium alloy, and the crossbeam 21 is a one-piece molded structure, as is the backrest. This reduces the number of parts in the seat bracket 2, thereby reducing assembly steps and improving assembly efficiency.

[0085] In some examples, the width of the backrest gradually decreases from the end closest to the crossbeam 21 toward the end furthest from the crossbeam 21.

[0086] In some examples, the cross-sectional shape of the beam 214 can be similar to that of the channel steel, forming an open-on-one structure, which facilitates the setting of the mold during casting. To enhance the strength of the beam 214, reinforcing ribs can also be provided inside the beam 214.

[0087] In some implementations, see Figure 2 and Figure 4 The crossbeam 21 and / or the backrest 22 are provided with reinforcements.

[0088] In the above design, the crossbeam 21 is reinforced to enhance its strength. The backrest 22 is also reinforced to enhance its strength.

[0089] In some examples, the crossbeam 21 is provided with a reinforcing section. The reinforcing section includes a cross-shaped reinforcing rib 201. For example, the cross-shaped reinforcing rib 201 can be provided at the first connection 213 and the support 211 of the crossbeam 21 to improve the strength of the connection between the crossbeam 21 and other components.

[0090] In some examples, the beam 21 is provided with a reinforcing section, which includes a first tie rod 202. For example, the tie rod can be provided between the first connection 213 and the support 211, or it can be provided between the support 211 and the beam body 214.

[0091] In some examples, the crossbeam 21 is provided with a reinforcing section, which includes a flange structure 204. For example, a flange structure 204 protruding towards the connecting structure 1 is provided on the edge of the support 211 to improve the load-bearing performance of the support 211. In addition, when the support 211 is connected to the body 100 of the vehicle 1000 by bolts, the distance between the flange structure 204 and the bolt hole on the support 211 can be controlled. One side of the nut is placed against the flange structure 204, and the flange structure 204 prevents the nut from rotating when the bolt and nut are connected, thus improving the ease of connection.

[0092] In some examples, the backrest 22 is provided with a reinforcing part, which includes a second tie rod 203. For example, the backrest 22 includes a back panel 221 and a frame 222, and a second tie rod 203 is provided between the back panel 221 and the frame 222 to improve the stress resistance of the backrest 22.

[0093] In some examples, both the backrest 22 and the crossbeam 21 are provided with reinforcing parts. These reinforcing parts can be configured as described in the above embodiments, and will not be repeated here.

[0094] In the description of the embodiments of this application, specific features, structures, materials or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0095] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
